user entities not created in content dir on tome:export

Problem/Motivation

drush tome:export -y creates a content export missing users, that can not be installed with drush tome:install

Steps to reproduce

1. Open this project in gitpod
https://gitpod.io/#https://github.com/Realityloop/starterkit-drupal-foun...

2. Once the install process has completed, break terminal with CTRL/CMD+C

3. Change to the drupal directory
cd ../drupal

4. Enter DDEV ssh
ddev ssh

5. Optionally confirm Tome import works
drush tome:import -y

6. Update tome to 1.9
composer require 'drupal/tome:^1.9'

7. Clear cache for good measure
drush cr

8. Execute Tome Export after update
drush tome:export -y

Structure of generated meta/index.json

{
    "consumer.a72faba4-778b-4b9a-a867-cefeff170d1c": [
        "user.71ff0341-88b1-40c6-bf6a-1131b20cd36a"
    ]
}

9. Inspect drupal/content directory in the gitpod IDE's file explorer and see that there are no user entities

Only 1 file gets created in content dir, in my instance this was consumer.a72faba4-778b-4b9a-a867-cefeff170d1c.json

10. Execute Tome import and see that it will fail
drush tome:install -y

gitpod@DruxtFoundry-web:/var/www/html$ drush tome:install -y

 // You are about to DROP all tables in your local database and re-install Tome. Do you want to continue?: yes.
